Title: Confidence and frame signal quality detection in a soft decision convolutional decoder
Inventor: WONG DANNY YUK-KUN
IPC: H03M13/35
Filed: 1996-10-03
Abstract: Received signals are processed (111) to generate confidence measure signals.  Before these are forwarded to a soft decision decoder (116), correction factors are applied, e.g. by a look-up table (113), to reduce the extent to which the signals differ from a logarithmic representation of the error statistics of the received signals. Alternatively, or as well, the confidence measure signals may be summed (122) and thresholded (123) to provide a quality-indicating signal. In a coder, error check bits for a frame of bits to be convolutionally coded are generated from bits taken from the beginning and end of the frame but not the middle.

Title: Traffic management in packet communication networks having service priorities and employing effective bandwidths
Inventor: WHITT WARD
IPC: H04L12/56
Filed: 1998-04-27
Abstract: A method is provided for admitting new requests for service in a shared resource having a capacity. The new request has service priority levels associated therewith. In one embodiment of the invention, for example, the shared resource may be a packet communications network and the service request may be a request to admit a new connection. The method proceeds as follows. First, for each service priority level on said shared resource, a total effective bandwidth is generated which is represented by a sum of individual effective bandwidths of previously admitted requests for service. Subsequent to receiving a new request for service having aspecified priority of service level, a plurality of effective bandwidths are accessed for the new request. The plurality of effective bandwidths are respectively associated with the specified service priority level and service priority levels therebelow. The new request is admitted if, for the specified service priority level and for each service priority level therebelow, the sum of (i) said total effective bandwidth for a given service priority level and (ii) for said new request, the effective bandwidth at the given service priority is less than the capacity.

Title: System for filtering medical and biological fluids
Inventor: STERNBERG SHMUEL
IPC: B01D63/16
Filed: 1997-09-22
Abstract: A method and apparatus for filtering suspensions of medical and biological fluids, one aspect of which is separating a suspension comprising at least two types of particles (104) and (108) which are differently sized or shaped and in which a first type of red cell particle (104) may be deformable at a relatively lower force and/or faster rate than a second type of white cell particle (108). A filter membrane (100) is provided having pores (102) with substantially precisely dimensioned pore sizes, with the pores (102) being dimensioned to allow passage of the first type of particle (104) without distortion or only minimal distortion and passage of the second type of particle (108) only with substantial distortion.      Because the filter membrane (100) has precisely dimensioned pores (102), with spacing between the pores (102) being maintained despite the smaller interval between the pores (102), the porosity of the membrane (100) may be relatively much greater, allowing faster filtration rates while reducing shear exposure time and consequently reducing particle damage. Various methods for preventing clogging of the membrane (100) are also disclosed.

IPC: D04H18/04
Filed: 1998-08-04
Abstract: A technique and apparatus for providing reciprocating hydroenhancement includes a pair of fabric spools with a hydroenhancement process disposed therebetween. The hydroenhancement process is configured to impart a minimal amount of hydroenhancement to the fabric passing therethrough and may comprise only a single vacuum roll and associated single hydroenhancement jet (other arrangements may use two or three of vacuum rolls and jets in order to provide controllable "front side" and "back side" treatments on a per pass basis). The fabric to be treated is loaded onto a first spool, passes through the hydroenhancement process and is thereafter taken up on the second spool. Once the entire length of fabric has been treated and loaded onto the second spool the process is reversed; the fabric is unwound from the second spool, treated a second time and re-loaded onto the first spool. The process is reversed once again, and a second "forward" treatment is imparted to the fabric. This "back and forth" (i.e., "reciprocating") hydroenhancement process is continued until the desired degree of hydroenhancement has been achieved. Measuring units (such as a permeability measuring system) may be used to evaluate the hydroenhancement on each pass to control various process parameters, as well as to determine when to stop the process.

Title: Charge sensitive amplifier with high common mode signal rejection
Inventor: MALLINSON MARTIN
IPC: H03F3/45
Filed: 1997-11-13
Abstract: A charge sensitive amplifier with high common mode signal rejection includes an NPN bipolar junction transistor (BJT) and a P-channel metal oxide semiconductor field effect transistor (MOSFET) connected in a totem pole circuit configuration. The BJT base terminal receives a dc reference voltage, the MOSFET gate terminal receives the incoming data signal, the MOSFET drain terminal is grounded and the BJT collector terminal provides the output voltage signal and is biased by the power supply through a resistive circuit element. The MOSFET operates as a source follower amplifier with the transconductance of the BJT serving as the load at the source terminal, while the BJT operates as a common emitter amplifier with the transconductance of the MOSFET providing emitter degeneration. The signal gains of such source follower and common emitter amplifiers are substantially equal and of opposite polarities. Therefore, any common mode signal components due to common mode input signals present at the input terminals (i.e., the BJT base and MOSFET  gate terminals) which would otherwise appear within the output signal are substantially cancelled, thereby resulting in a high degree of common mode signal rejection.

Title: A building member
Inventor: LA GROUW CORNELIS
IPC: E04B2/32
Filed: 1998-12-09
Abstract: A building member is formed from a pair of spaced apart boards connected between the opposed faces by narrow connecting members which extend the length thereof. The edges of the connecting members are preferably retained within channels in the opposed faces of the wooden boards. The boards and the connecting members enclose an insulation space which may be filled with an insulation material. A selection of advantageous connection profiles is disclosed for the connection between the edge of the connecting member and the channel of a board. One of the boards may instead comprise an extruded siding, for example of aluminium or plastic, with a leg extending perpendicularly from the siding forming the connecting member. The building member may be constructed in a simple process and reduces wastage of material which often occurs in forming laminated solid timber building products while offering enhanced insulative properties.
